Counter-Terrorism and Security Bill

My Lords, I think there may be different types of transit. There are certainly some instances in an airport where you pass through and do not actually go through immigration control. You are simply passing from one airline service to another and you bypass the place where the police officer would be to seize your passport. Other people in transit may have to remain for a while, possibly because they want to see somebody or collect luggage. It may well be that the noble Lord is entirely right that in that situation, because you are confronted by a constable with the power, the power would be exercisable —so it may depend very much on the circumstances of the individual traveller.
